MATLAB Function Reference

trimesh

Triangular mesh plot

Syntax

• trimesh(Tri,X,Y,Z)
  trimesh(Tri,X,Y,Z,C)
  trimesh(...'PropertyName',PropertyValue...)
  h = trimesh(...)
  

Description

trimesh(Tri,X,Y,Z) displays triangles defined in the m-by-3 face matrix Tri as a mesh. Each row of Tri defines a single triangular face by indexing into the vectors or matrices that contain the X, Y, and Z vertices.

trimesh(Tri,X,Y,Z,C) specifies color defined by C in the same manner as the surf function. MATLAB performs a linear transformation on this data to obtain colors from the current colormap.

trimesh(...'PropertyName',PropertyValue...) specifies additional patch property names and values for the patch graphics object created by the function.

h = trimesh(...) returns a handle to a patch graphics object.

Example

Create vertex vectors and a face matrix, then create a triangular mesh plot.

• x = rand(1,50);
  y = rand(1,50);
  z = peaks(6*x-3,6*x-3);
  tri = delaunay(x,y);
  trimesh(tri,x,y,z)
